Ideal dont stock them, well they tell me they dont.
Got one from animates yesterday, $80 odd but it has a probe. Just need to find a 2nd one, they look to be re branded so just need to find a cheaper one out there. May try and DIY one.
Interesting how different stores have different service. First store was useless at best and didnt offer to track one down. Reptile section was not below the "Reptile" sign but 10m away.
The 2nd one(MT Eden) was fantastic and they went out of their way and checked on the computer and found what i needed in their store room. They where also interested in what i was going to use them for.
